Overview
Process mining is an emerging discipline that aims at developing novel methods to discover knowledge from process execution data (stored in the format of event logs) and support evidence-based business process improvement. Specifically, process mining can be used for the task of discovering organizational models, providing insights on organizational structures and human resource (employee) performance. At the core of this task is cluster analysis, with challenges unique to process execution data.
Most state-of-the-art process mining techniques address this task through first learning resource features and then discovering resource clusters. However, with these two phases performed separately, such an approach introduces additional complexity and lacks in computational efficiency, hindering application of the techniques. A different approach to the problem is needed.
Research engagement
- Literature review
- Lab-based computational experiments
- Report writing
Research activities
- Literature review on cluster analysis techniques
- Literature review on the key work of organizational model mining
- Exploratory data analysis and data cleaning
- Developing and testing computer algorithms
Outcomes
In this project, we will develop a novel algorithm to discover organizational models from event logs, based on the idea of biclustering. This algorithm is expected to simultaneously tackle the challenges of characterizing resource features and constructing resource clusters. It should be able to provide a robust solution to the problem, ensuring comparable effectiveness and high computational efficiency with respect to the state-of-the-art methods.
Skills and experience
- Knowledge on data mining, specifically cluster analysis
- Programming using Python and familiarity with the NumPy ecosystem
- Knowledge on process mining and/or business process management is preferred
